Matching is exact: x$nam is an error rather than a quiet hit on name,
which is what a plain list would do.
Usage
# S3 method for class 'typed_instance'
x$name
# S3 method for class 'typed_instance'
x[[i, ...]]
Arguments
- x
An instance.
- name, i
A field name, or a position.
- ...
Ignored.
Examples
Card <- struct("Card", holder = chr[1], number = chr[1])
cc <- Card(holder = "Ada", number = "4111")
cc$holder
#> [1] "Ada"
cc[["number"]]
#> [1] "4111"
try(cc$holdr)
#> Error : <Card> has no field `holdr` -- did you mean `holder`?
#> fields: holder, number
